Invalid Quaternion in transform at startup

[mrivi]

We get a bunch of this errors at startup on all 3 planners. We need to figure out where are they coming from.

[ERROR] [1569826119.454300726, 0.856000000]: Ignoring transform for child_frame_id "fcu" from authority "unknown_publisher" because of an invalid quaternion in the transform (0.000000 0.000000 0.000000 0.000000)

I tried a few things:

• happens also with older versions of mavros e.g. 0.30.0
• doesn't happen on hardware

Hi @mrivi , have you figured out why it happens in software?

[mrivi]

No, I didn't investigate further since they aren't creating any issues. We look further in the future.

Figured out where it comes ffrom PX4/PX4-Autopilot#13182
